From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone

Journal of Quaternary Science, Volume 41, Issue 6, Page 888-895, August 2026.
ABSTRACT The Altar Stone, the 6000 kg central sandstone megalith at Stonehenge in southern England, is suggested to have originated from the Orcadian Basin in northeast Scotland, some 700 km away. However, its source location within this large basin remains unresolved and its mode of transport uncertain.

Centennial‐scale phosphorus accumulation drives regeneration and internal loading in a boreal lake

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Legacy anthropogenic phosphorus (P) accumulated in sediments drives internal P loading in eutrophic lakes. However, predicting the temporal response of internal P loading to the external loading reduction is difficult due to the complexity of sedimentary P cycling. In this study, we use geochemical profiles obtained from a 180‐cm sediment core

Effect of Intrinsic Carbon in Hot Briquetted Iron on Melting and Refining Efficiency under Electric Arc Furnace Conditions for Sustainable Steelmaking with Active Use of H2‐Reduced Iron

steel research international, Volume 97, Issue 8, Page 4126-4137, August 2026.
The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...
